5d10

5d10 is a dice rolling mechanic commonly found in tabletop role-playing games and other games of chance. It represents the act of rolling five ten-sided dice and summing their results. Each die in a 5d10 roll has faces numbered from 1 to 10, inclusive.

The minimum possible result when rolling 5d10 is achieved when all five dice land on 1, yielding a total of 5. The maximum possible result occurs when all five dice land on 10, resulting in a total of 50. The average result of a single ten-sided die is 5.5. Therefore, the expected average result of rolling 5d10 is 5 multiplied by 5.5, which equals 27.5.

The distribution of possible outcomes for 5d10 is a bell curve, meaning that results closer to the average of 27.5 are more probable than results at the extreme ends of the spectrum (5 or 50). This distribution is a consequence of the central limit theorem, which states that the sum of a large number of independent random variables tends towards a normal distribution.

In game contexts, 5d10 can be used to determine damage, skill check successes, or other random outcomes. The range of possible results offers a considerable degree of variability, allowing for a wide spectrum of potential effects within a game. The mechanic provides a greater spread of results compared to rolling fewer dice or dice with fewer sides, and a smoother curve than rolling dice with very few sides.
